Description
The present invention provides fragrance precursor compounds. In particular, the invention provides a method for the use of several classes of compounds which can act as fragrance precursors in cosmetic products, such as deodorants and antiperspirants. These compounds can also act as fragrance precursors in laundry products such as detergents and fabric softeners. The compounds are normally odorless or nearly so, but upon contacting the skin as, for example, in skin care compositions or in personal care compositions, produce fragrances. The compounds also produce fragrances when used in the presence of lipases, e.g. in laundry products.
A principal strategy currently employed in imparting odors to consumer products is the admixing of the fragrance directly into the product. There are however, several drawbacks to this strategy. For example, the fragrance material can be too volatile, resulting in fragrance loss during manufacturing, storage, and use. Many fragrance materials are also unstable over time. This again results in loss of fragrance during storage.
In some cases, fragrances are microencapsulated or treated with cyclodextrins to form inclusion complexes to help decrease volatility and improve stability. However, these methods are for a number of reasons often not successful. In addition, cyclodextrins can be too expensive.
In many consumer products it is desirable for the fragrance to be released slowly over time. Microencapsulation and cyclodextrins have been used to provide slow-release properties, however, they are subject to the same limitations associated with the use of cyclodextrins as stated above.
The Japanese Patent Application No. 07/179 328 discloses sustained release of aromatic compounds which are perfume derivatives for control of perspiration. The compositions perfume when they are gradually decomposed by bacteria usually residing on the body surface, resulting in a long, stable perfuming effect. A preferred derivative is said to contain one or a mixture of phosphoric ester, amino acid and carboxylic derivatives of perfumes. The active fragrancing substance, i.e. an alcohol, an aldehyde or a ketone, is released slowly after laundering a fabric to prolong the fragrancing of the fabric after laundering.
The PCT Application WO 95/04809 discloses the use of esters for scenting fabrics being washed in the presence of a lipase-containing detergent.
The PCT application WO 96/1999119 describes the addition of silicone polymers to perfumes to improve surface residuality of a fragrance. The fragrance is not bound to the polymer.
U.S. Pat. No. 3,215,719 describes silicate esters of essential alcohols where the oxy group RO— of an alcohol is directly bonded to silicone as Si—OR which can be applied to textiles to impart thereto a lasting fragrance.
The present invention provides compounds which have a low level of odor, or are even odorless, prior to application to the skin, but which release odorant molecules after application to the skin. That is, they provide a delayed release of the fragrance, in particular as they react with microorrganisms present on the skin, i.e. Axilla bacteria. The compounds of the present invention also release odorant molecules when used in the presence of lipase-containing products.
The compounds of the present invention are organosiloxane compounds having at least one unit of the formula
or a mixture thereof. In addition, if any other unit(s) in the siloxanes is/are present this/these unit(s) have the following formula
wherein R represents a substituted or unsubstituted C1-8 alkyl group or a substituted or unsubstituted aryl group; R″ represents a hydrogen atom, a monovalent C1-8 hydrocarbon group or a monovalent C1-8 halogenated hydrocarbon group; R1 represents a hydrogen atom, a substituted or unsubstituted C1-8 alkyl group or a substituted or unsubstituted aryl group or a bond connecting CR1 and CR3; R3 represents a hydrogen atom or a substituted or unsubstituted C1-8 alkyl group, or a substituted or unsubstituted aryl group; A represents (CR4 2)n whereby R4 represents a substituted or unsubstituted C1-8 alkyl group, a substituted or unsubstituted aryl group, or a hydrogen atom, n is from 0-20, preferably 1 to 10, and each R4 is the same or different; OR2 represents the residue of an olfactive alcohol or of the enol form of an olfactive aldehyde or olfactive ketone; is 0, 1 or 2; and is 0, 1, 2 or 3.
In the general formula of the organosiloxane compounds of the invention, R may be for example methyl, ethyl, butyl or phenyl. R″ may be for example alkyl, alkenyl, aryl, alkaryl, aralkyl and halogen substituted alkyl, alkenyl, aryl, alkaryl and aralkyl. Specific examples are methyl, ethyl, vinyl, phenyl and 3,3,3-trifluoropropyl. R4 preferably is a hydrogen atom or methyl. It is preferred that at least 80% of all R and R″ groups are methyl groups.
In addition, is preferably 1, while is preferably 2, making either a substantially linear organosiloxane compound or a cyclic diorganosiloxane polymer. However, if the diorganosiloxane is a substantially linear polymer, at least two endblocking units must be present, thus requiring the presence of two units when is 2, two units when the value of is 3, one unit when is 2 and one unit when is 3. Therefore, suitable preferred polymers have either the general formula
wherein R and R″ are as defined above; X denotes a group Y or a group R″; and Y denotes a group of the formula Ia or Ib, is from 0 to 1000; is from 0 to 1000, whereby at least one X denotes Y in the case that =0; has the value of from 0 to 10; and has the value of from 1 to 10. Preferably is from 3 to 6. Further embodiments occur when is greater than 3, or has a value of at least 3.
The organosiloxane compounds of the present invention have at least one unit falling within the general formula Ia or Ib. Suitable organosiloxane compounds include polymeric materials, which may be homopolymers consisting only of such units Ia or Ib or copolymers containing in addition units having the general formula II.
The compounds of formula Ia or Ib are not limited to any particular stereoisomers, all possible stereoisomers as well as racemates are thus included within the scope of formula Ia or Ib.
The units of formula Ia or Ib may be distributed randomly in an organosiloxane copolymer. Units of formula Ia or Ib may be end-blocking units of these polymers or they may be located at both the end of the copolymer and in the chain of the copolymer.
The organosiloxane compounds may vary from freely flowing liquids to highly viscous gum-like materials to resinous solids. Preferred, at least for cosmetic applications, are monomers or liquid, substantially linear, organosiloxane homopolymers and copolymers, most preferably those having a viscosity of from 25 to 500 mm2/s since these are more easily mixed with other ingredients to make cosmetic compositions and they will spread more easily onto the skin.

It is a matter of course that it is not possible to give complete lists of the odoriferous alcohols or aldehydes or ketones which are liberated as a result of the desired cleavage of the compounds of formula Ia or Ib, e.g. by bacteria, in particular axilla bacteria, or lipases and which alcohols, aldehydes and ketones are then capable of imparting agreeable odors. The skilled artisan is, however, quite aware of those alcohols, aldehydes and ketones which provide a positive contribution to the fragrance compositions.
The compounds of formula Ia and/or Ib are preferably used as sustained release odorants but also to mask or attenuate undesirable odors or to provide additional odors not initially present in consumer products, i.e. cosmetic products destined for application to human skin such as underarm deodorants or antiperspirants or other deodorants contacting the body, or in hand lotions, baby powders, baby lotions, ointments, foot products, facial cleansers, body wipes, facial make-up, colognes, after-shave lotions, shaving creams, etc. Additional applications include laundry detergents, fabric softeners, fabric softener sheets, automatic dishwasher detergents, and other lipase-containing consumer products.
The compounds of formula Ia and/or Ib are virtually odorless under normal temperature, i.e. at about 10-50 degrees Celsius, and at atmospheric conditions and about 20 to 100% relative humidity. However, when applied to the body or when used in an application in the presence of lipases, they undergo a transformation in which the fragrant alcohol or aldehyde or ketone is released.
As said before, the compounds of formula Ia and/or Ib, upon cleavage, provide alcohols, aldehydes, and ketones having organoleptic properties and therefore permit the development of methods useful in presenting or enhancing the odor of consumer products. These compounds may be used individually in an amount effective to enhance the characteristic odor of a material. More commonly, however, the compounds are mixed with other fragrance components in an amount sufficient to provide the desired odor characteristics.
The amount required to produce the desired, overall effect varies depending upon the particular compound(s) of formula Ia and/or Ib chosen, the product in which it will be used, and the particular effect desired.
For example, depending upon the selection and concentration of the compound chosen, when a compound of formula Ia or Ib is added either singularly or as a mixture, e.g. to a deodorant or laundry product composition at levels ranging from about 0.1 to about 10% by weight, or most preferred about 0.25 to about 4% by weight, an odorant, i.e. an odoriferous alcohol or aldehyde or ketone, in an organoleptically effective amount is released. This newly formed odorant produces or serves to enhance the odor of the fragrance.
The compounds of formula Ia and/or Ib can accordingly be used in the manufacture of odorant compositions used in the preparation of cosmetic and laundry products, e.g. deodorants, antiperspirants, laundry detergents, fabric softeners, and as is evident from the above compilation, a broad range of known odorants or odorant mixtures can be used. In the manufacture of such compositions the known odorants or odorant mixtures set forth above can be used according to methods known to a person skilled in the art, normally a perfumer, or as described, e.g. in W. A. Poucher, Perfumes, Cosmetics, Soaps, 2, 7th Edition, Chapman and Hall, London 1974.
The compounds of formula Ia or Ib can be prepared by using standard methods known to a person skilled in the art. For example the method disclosed by U.S. Pat. No. 5,550,272 can be used. The organosiloxane compounds of the present invention can be prepared by the reaction of an organosiloxane having at least one unit of the general formula
with an unsaturated ester or enol ester having a radical OR2 of a fragrant alcohol, aldehyde or ketone, a compound of the general formula
Esters of the general formula III may be prepared from the corresponding carboxylic acids and alcohols by standard methods known per se. (For example see, Comprehensive Organic Chemistry, Derek Barton and W. David Ollis, eds. Vol. 2, 1979, pp.871-907). For example, esters are formed by the acid catalyzed reaction between a carboxylic acid and an alcohol. During the condensation, water is usually removed.
Either protic or Lewis acids may be used. Some acids which may be used are p-toluensulfonic acid, sulfuric acid, and pyridinium p-toluenesulfonate. A variety of inert solvents may be used such as toluene, xylene, cyclohexane, and hexane.
In another example, a carboxylic acid and an alcohol react to form an ester when treated with N,N′-dicyclohexycarbodiimide and 4-pyrrolidinopyridine. (For example see, the procedure of Hassner and Alexanian in Tetrahedron Letters 4475, (1978)).
Enol esters of the general formula III may be prepared using the procedure of J. Chem. Soc., Perkin Trans. I, 2509 (1993).
The preferred preparation of organosiloxane compounds of the type Ia or Ib comprises reacting a compound of the general formula III and an organosiloxane compound having at least one unit of the general formula IV, any other units present being those represented by the general formula II.
The reaction is preferably carried out employing stoichiometric proportions of compounds III and IV or a slight stoichiometric excess of compound III. However, a stoichiometric deficiency of compound III can be employed if residual silicon-bonded hydrogen is desired in the product.
The reaction between compounds III and IV may be carried out employing known procedures for the addition of silicon-bonded hydrogen atoms to groups containing aliphatic unsaturation. Thus, such reactions are generally catalyzed by a platinum group metal or a compound or complex of such a metal. Examples of catalysts which may be employed in the reaction between compounds III and IV are platinum on carbon, chloroplatinic acid, platinum acetyl acetonate, complexes of platinum compounds with unsaturated compounds, e.g. olefins and vinyl siloxanes, complexes of rhodium and palladium compounds and complexes of platinum compounds supported on inorganic substrates. The addition reaction may be performed at reduced, atmospheric or increased pressure. It is generally preferred to employ a solvent, e.g. toluene or xylene in the reaction mixture although the presence of a solvent is not essential. It is also preferred to carry out the reaction at elevated reaction temperatures e.g. ranging from room temperature up to the reflux temperature of the reaction mixture.
